Influenza vaccine: These symptoms are not generally associated with this killed virus vaccine, and would strongly recommend that you see a doctor asap and find out what else may be going on. Their onset may simply be coincidental with your receipt of the vaccine. ...Read more

Flu Shot (Definition)

Also known as influenza vaccines, flu shots are given out once a year to protect against the flu. The flu shot stimulates the immune system to build antibodies to three or four strains of flu viruses in the hopes that it will offer protection from the current strains present in the community. Each year the Centers for Disease Control (CDC) monitors the strains of Influenza globally and incorporates the appropriate antigens in the new vaccine. For best protection the vaccine ...Read more

Yes and no: There is no active virus in the vaccine but in some people it "stimulates" a memory and they can develop serious flu like symptoms. On occasion people with allergies to egg protein etc can have a reaction but it sounds to me like the former. Another possibility is a coincidental viral infection but in my experience it is the "memory" explanation that often explains best this phenomenon. ...Read more

Mgt: I would suggest having a flu test to confirm influenza. I would advise a course of anti influenza medication, since he may have the flu. Asthmatics are prone to worsening with this viral illness. If the breathing treatments are not helping a course of steroids may be used. ...Read more

Flu shot 3 days ago, gas, nausea, runny nose, headache, mild chest pain, weakness, sweating/chills, and dizzy. If not flu shot then what?

FLU: Flu vaccine itself can give rise to mild flu-like symptoms as you mentioned here (much easier/ milder than flu itself). Drink a lot of fluid, take enough rest. Can have Ibuprofen or Acetaminophen for aches and fever (no aspirin). Hope you will feel better soon. ...Read more

I got my flu shot a few months ago now I'm sick with everything even a cough that hurts my back and chest. Should I go to the doctor?

Probably...: The flu shot is not a live vaccine and is unlikely to be the cause of your symptoms. Your cough can be due to many diagnoses so you need to see your doctor for diagnosis and treatment. A cough can lead to musculoskeletal discomfort that will resolve once the cough is gone. ...Read more

I've woken up w sore throat/bad chest. Can I still go to gym & workout? Or will this make me sicker? I feel fine other than chest/throat. I’ve had flu shot

Hard to guess: Throat pain can be from strep throat infection (antibiotics are needed), a cold or influenza (antibiotics usually not used), or from some other cause such as allergies or irritants. Usually, one sees a doctor if the sore throat is bothersome, recurrent, or doesn't go away quickly (mainly to see about antibiotics). Lots of coughing makes it less likely to be strep throat. Best to rest a few days. ...Read more

Viral exanthem: This could be a viral rash, but you can't discount other possible causes exanthems can be caused by toxins or drugs, microorganisms, or can result from autoimmune disease. It could be related to the flu shot, but not necessarily.

A visit to the medical doctor could be warranted here. ...Read more

Do babies get antibodies in breast milk after mom gets a flu shot?

Do babies get antibodies in breast milk after mom gets a flu shot?

Not enough: The antibodies in breast milk are predominantly IgA, otherwise called gut antibody, because they help prevent germs from attaching & invading the gut wall. Mothers make IgG after a flu shot, and a little comes across in BM but not enough to be considered protective. If the kid is 6 mo they can get a flu shot. Before then we encourage any of their contacts to get one to "cocoon" baby in protection. ...Read more

Pregnancy is when...: ....you're pregnant.
